The given statement is false. Plague can be transmitted from animals to humans as well as humans to humans.

Plague is a type of infectious disease caused by bacteria Yersinia pestis and it affects rodents, some animals and human beings. Human beings are infected by plague on being bitten by flea which is infected with the bacteria causing plague.

On direct contact with the infectious tissues or fluids of animals infected or have died due to plague also increases the risk of being infected by plague. By inhaling respiratory droplets of the humans or animals in close contact infected by plague increases the chances of infection in humans.

A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied t
andreev551 [17]

5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

<h3>Given</h3>

Mass of oxygen at room temperature =500.0 ml

Volume of pressure = 50 atm pressure.

The gas to a volume = 150.0 ml

<h3>Explanation</h3>

The volume decreases by the factor = 500.0 mL / 150.0 mL

                                                             = 10 / 3

The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to

P_{final} = \frac{10}{3} * 1.50 atm

          = 5.00 atm

So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

Does hot water tend to rise or sink? Explain.
Mademuasel [1]

Answer:

When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.

Explanation:

When you heat up water, the water molecules start moving around faster and faster. ... So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top.
